Best Ground Covers for Guanacaste: Top 5 Low-Maintenance Options That Actually Thrive in Dry Coastal Conditions
If you’ve ever tried to keep a garden looking green in Guanacaste all year…
You already know this is not a “normal” environment.
This is not Costa Rica rainforest.
This is:
- long dry season
- intense sun
- strong winds
- and in many areas… salty air
So when people ask:
👉 “What ground cover should I use?”
The answer is NOT simple.
Because here’s the truth:
👉 most ground covers look good for 2–3 months… and then reality hits.
I’m Joan Alvarado, agronomist engineer, and after working on landscaping projects across Tamarindo, Flamingo, Conchal and surrounding areas, I’ve tested ground covers in real conditions — not greenhouse conditions, not “catalog photos”.
Real Guanacaste.
These are the ones that actually perform.
Mani Forrajero (Arachis pintoi) — The Most Functional Ground Cover You Can Use
If I had to design a landscape in Guanacaste that balances:
- aesthetics
- soil improvement
- water efficiency
👉 Maní forrajero would almost always be part of the solution.
And this is not hype — this is agronomy.
🌱 What makes it different (technical level)
Arachis pintoi is a leguminous plant, which means it has a symbiotic relationship with rhizobium bacteria.
👉 Translation:
It captures nitrogen from the air and converts it into usable nutrients in the soil.
In Guanacaste soils — which are often:
- low fertility
- sandy
- degraded
👉 this is extremely valuable.
You are not just covering soil…
👉 you are improving it.
🌿 Growth behavior
- Creeping, horizontal growth
- Forms a dense mat over time
- Produces small yellow flowers (nice bonus)
It expands gradually, but once established:
👉 it dominates the space
💧 Water management
During establishment:
- requires consistent irrigation
- especially first 6–8 weeks
After establishment:
👉 becomes very efficient
BUT — and this is important:
If you want:
- dense
- dark green
- premium look
👉 you still need proper irrigation design
⚠️ Common mistakes
- Planting in compacted soil
- Not irrigating during establishment
- Expecting instant coverage
This is a system plant, not a quick fix.
📍 Best uses
- under trees
- around palms
- large low-traffic areas
- replacing traditional grass
🧠 Real talk
If someone tells you:
“this is zero maintenance”
👉 they are lying 😅
But compared to grass?
👉 it’s a massive upgrade
Zoysia Grass (Zoysia spp.) — The High-End Lawn Alternative
Zoysia is what I recommend when a client says:
👉 “I want a lawn… but I don’t want problems”
And in Guanacaste, that’s basically everyone 😅
🌱 Technical characteristics
Zoysia is a warm-season grass with:
- slow vertical growth
- dense horizontal spread
- high root depth
This combination makes it:
👉 extremely stable in dry environments
🌿 Growth behavior
- grows slower than most grasses
- creates a thick, uniform surface
- suppresses weeds naturally
💧 Water efficiency
This is where it shines:
- requires significantly less water than traditional lawns
- holds moisture better due to density
BUT:
👉 during dry season, irrigation still defines quality
Without it:
- it survives
- but loses that “perfect green” look
⚠️ Important considerations
- higher installation cost
- slower to establish
- needs proper base preparation
If you install it badly…
👉 you will regret it
📍 Best uses
- residential lawns
- villas
- areas with foot traffic
🧠 My opinion
If budget allows:
👉 Zoysia is one of the best lawn systems you can have in Guanacaste

Wedelia (Sphagneticola trilobata) — The Fastest Coverage You’ll Ever See
This plant doesn’t wait.
It takes over.
🌱 Technical characteristics
Wedelia is a fast-growing creeping plant with:
- aggressive horizontal spread
- strong vegetative propagation
- high adaptability
🌿 Growth behavior
- spreads rapidly
- fills empty spaces fast
- produces bright yellow flowers
This makes it ideal for:
👉 fast landscaping results
💧 Water requirements
- moderate
- adapts well once established
⚠️ Critical warning
Wedelia is:
👉 invasive if unmanaged
If you don’t:
- prune
- contain
- monitor
👉 it will invade other areas
📍 Best uses
- slopes (excellent erosion control)
- large open areas
- quick coverage zones
🧠 Reality check
This is not a “delicate design plant”
This is:
👉 a control it or it controls you plant 😅
Used correctly:
🔥 extremely effective
Lippia (Phyla nodiflora) — The Tough, Walkable Ground Cover
This is one of those plants people overlook…
Until they see it working.
🌱 Technical characteristics
Lippia is:
- drought tolerant
- low-growing
- capable of handling compaction
🌿 Growth behavior
- forms a dense, carpet-like layer
- stays relatively low
- spreads evenly
💧 Water efficiency
- very low water requirement
- ideal for sustainable landscapes
⚠️ Limitations
- not as visually “perfect” as grass
- can look uneven in early stages
📍 Best uses
- walkable areas
- eco-landscapes
- low-maintenance gardens
🧠 Real perspective
If your goal is:
👉 functionality + low water + durability
This is one of the best options.
Dichondra (Dichondra repens) — Soft, Elegant and Design-Focused
This one is for clients who care about:
👉 aesthetics
🌱 Technical characteristics
Dichondra is:
- low-growing
- soft-leaved
- shallow-rooted
🌿 Growth behavior
- forms a smooth green carpet
- very visually clean
- low height
💧 Water requirements
- moderate
- requires good drainage
👉 very sensitive to overwatering
⚠️ Limitations
- does NOT tolerate heavy traffic
- sensitive to poor soil conditions
- requires controlled environment
📍 Best uses
- decorative areas
- around stepping stones
- modern landscapes
🧠 Honest truth
This is not a “rugged Guanacaste plant”
This is a:
👉 controlled environment plant
But when used correctly?
🔥 looks premium
Final Thoughts
If there’s one thing Guanacaste teaches you fast…
👉 it’s that plants don’t care about your design ideas
They care about:
- water
- soil
- climate
And if those don’t match…
👉 they will fail
The difference between a landscape that struggles…
and one that works effortlessly…
👉 is plant selection
Not trends
Not Pinterest
Not what looks good in San José
👉 what works HERE
And trust me…
👉 it’s much better to design a landscape that works with the environment
than to fight it every dry season 😅
THIS IS ALSO IMPORTANT
One thing that is important to understand is that even the best plants will struggle if water is not managed properly. In this region, irrigation is not just about watering. It’s about efficiency, distribution, and timing. I’ve seen many landscapes fail not because of plant choice, but because water was either insufficient, uneven, or poorly controlled. In a place where the dry season can last months without rain, every drop matters. And more importantly, how that water is delivered matters even more.
This is also very important
Another factor that people often underestimate is design. The way plants are arranged, their spacing, their exposure to sun and wind, all of that influences how they perform. A plant that works perfectly in one part of a property might fail in another simply because conditions are slightly different. That’s why landscape design in Guanacaste is not just aesthetic. It’s strategic.
